Post-Approval Studies (PAS) Database

The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Detailed Study Protocol Parameters
Study Design Description The objective of this study is to evaluate long term safety and effectiveness of the SJM™ Masters Series Hemodynamic Plus (HP) 15mm mitral mechanical heart valve as a replacement device for pediatric patients with a diseased, damaged, or malfunctioning mitral valve.

The study includes continued follow-up of patients enrolled in the HALO study, which was a single arm, prospective, non-randomized, multi-center clinical trial of the SJM™ Masters Series Hemodynamic HP 15mm mitral heart valve.

Study Population Description The study population consists of pediatric subjects that are 5 years or less in age with a diseased, damaged, or malfunctioning mitral heart valve.
Sample Size This study will continue to follow subjects that are alive and in which the valve is still implanted from the following groups:
Subjects enrolled in the HALO study,
Subjects enrolled under Continued Access, and
Emergency/compassionate use subjects who have consented for prospective follow-up.
Data Collection The following adverse events (if determined to be valve related and serious) will be summarized annually with descriptive statistics:
Hemorrhage (whether or not due to anticoagulant/antiplatelet medication);
Nonstructural dysfunction (including perivalvular leak, hemolysis, and hemolytic anemia);
Reoperation (including valve explant, not due to anatomical growth of the subject);
Structural valve deterioration;
Thromboembolism; and
Valvular thrombosis.
The following effectiveness endpoints will be reported at any/all time point(s) available:
Mean gradient as assessed by echocardiography;
Peak gradient as assessed by echocardiography; and
Valvular regurgitation grade as assessed by echocardiography.
Follow-up Visits and Length of Follow-up Study subjects will be followed annually either for five years from the date of implant, until subject withdrawal, or until end of device use, whichever occurs earliest.
